[removed] SyntaxError: missing ) after argument list

Question

I am getting the error:

SyntaxError: missing ) after argument list

With this javascript:

var nav = document.getE         


        

Answer 1

You got an extra } to many as seen below:

var nav = document.getElementsByClassName('nav-coll');
for (var i = 0; i < button.length; i++) {
    nav[i].addEventListener('click',function(){
            console.log('haha');
        } // <-- REMOVE THIS :)
    }, false);
};

A very good tool for those things is jsFiddle. I have created a fiddle with your invalid code and when clicking the TidyUp button it formats your code which makes it clearer if there are any possible mistakes with missing braces.

Answer 2

You have an extra closing } in your function.

var nav = document.getElementsByClassName('nav-coll');
for (var i = 0; i < button.length; i++) {
    nav[i].addEventListener('click',function(){
            console.log('haha');
        }        // <== remove this brace
    }, false);
};

You really should be using something like JSHint or JSLint to help find these things. These tools integrate with many editors and IDEs, or you can just paste a code fragment into the above web sites and ask for an analysis.
